通過回聲PHP找到deezer API藝術品

Question

我在論壇上發現了這個代碼php，我嘗試去適應我想要的，在this link裏有一個JSON，他們有關於我們搜索的藝術家的信息。但我想只提取這個功能cover_xl

"cover_xl":"https:\/\/cdns-images.dzcdn.net\/images\/cover\/1c7a7c081a1e7787321f81a889e9f7b8\/1000x1000-000000-80-0-0.jpg"

我一直試圖在許多方面，但沒有結果，所以我來問你的幫助。我也留下代碼來嘗試幫助解決方案。

<?php 
 
    $query = 'https://api.deezer.com/2.0/search?q=sam smith'; 
 
    $file = file_get_contents($query); 
 
    $parsedFile = json_decode($file); 
 
    $albumart = $parsedFile->data[0]->artist->picture[cover_xl]; 
 
?>

Answer 1

用下面的代碼我沒有你想要什麼：

<?php 

$url = 'https://api.deezer.com/2.0/search?q=sam%20smith'; 
$jsonStr = file_get_contents($url); 
$jsonArr = json_decode($jsonStr, true); 

$coverXlCollection = array(); 

foreach ($jsonArr['data'] as $row) { 
    $coverXlCollection[] = $row['album']['cover_xl']; 
} 

echo '<pre>'.print_r($coverXlCollection, true).'</pre>'; 

?> 

而結果是：

我做了一些修改您的代碼和我用json_decode()函數與第二個參數ameter true。在這種情況下，你的結果是數組而不是對象。

乾杯。
